These days, you can find just about anything on eBay, including this fossil of an infant Tyrannosaurus rex, which as a “buy it now” price of $2.95-million. It’s estimated to be 68-million years old, and was first discovered in 2013, on private land in Montana. It became the property of Alan Detrich, a professional fossil hunter who found it. In 2017, the fossil was lent to the University of Kansas Natural History Museum, where it was still on display when Detrich decided to put it up for auction. “Most Likely the Only BABY T-Rex in the World! It has a 15 FOOT long Body and a 21” SKULL with Serrated Teeth! This Rex was very a very dangerous meat eater. It’s a RARE opportunity indeed to ever see a baby REX,” according to the listing.

Scientists from Tel Aviv University (TAU), Israel have created the world’s first 3D vascularized, engineered heart with real human tissue and blood vessels. “This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” said professor and the study’s lead researcher Tal Dvir of TAU’s School of Molecular Cell Biology and Biotechnology, Department of Materials Science and Engineering in the Center for Nanoscience and Nanotechnology, and the Sagol Center for Regenerative Biotechnology.

NASA’s Cassini-Huygens spacecraft gathered radar data revealing that the small liquid lakes in Titan’s northern hemisphere are surprisingly deep, set atop hills and filled with methane, during its final flyby of Saturn’s largest moon in 2017. These lakes are more than 300 feet and provide new information about the way liquid methane rains on, evaporates from and seeps into Titan, the only other planetary body in our solar system known to have stable liquid on its surface. Titan’s hydrologic cycle is similar Earth’s, but rather than water evaporating from seas, forming clouds and rain, Saturn’s moon does it all with methane / ethane.

Most cameras today do not need manual adjustments to compensate for an increase or decrease in light, but rarely do we capture this in-action, that is until…now. A Reddit user yesterday posted a video of a ruler being flicked off the edge of a table, first in the shadows, and then in sunlight. In areas with less light, the camera automatically slows the shutter speed to gather enough light, while the opposite is true for well-lit areas. Read more to see the effect of this transition.
Researchers have discovered two new planets that might be orbiting the nearest star to our sun, a small red dwarf called Proxima Centauri, located approximately 4.24 light-years away from Earth. “We are pleased to show you, for the first time, what is for us a new candidate planet around Proxima that we call Proxima c,” said Mario Damasso of Italy’s Observatory of Turin on April 12 during the 2019 Breakthrough Discuss conference. It’s at least six times more massive than Earth, and the planet takes 1,936 days to orbit once around its star, thus making its average surface temperature much too cold for liquid water to flow.

Giant isopods are typically found in the cold, deep waters of the Atlantic, Pacific, and Indian Oceans. They have uniramous thoracic legs arranged in seven pairs, the first of which is modified into maxillipeds to manipulate and bring food to the four sets of jaws. A newly released video shows these creatures feasting on the corpse of an alligator, without having any issues breaking through its scaly skin. “They have this amazing ability to gorge themselves, store that energy and then basically not have another meal for months to years afterwards,” said Craig McClain of the Louisiana Universities Marine Consortium.

Google Maps is known for its “ichnographic,” or flattened out plan, where all buildings and their features appear perfectly perpendicular to a single, aerial viewpoint, thus enabling users to grasp a city’s entire layout, relative to its environs and the cardinal directions. Today, creating these maps aren’t too difficult, but Leonardo da Vinci managed to make one of Imola, Italy way back in 1502. Read more for a video showing how he did it.
SpaceX’s Falcon Heavy is currently the world’s most powerful operational rocket, and today, it launched its first commercial mission from Florida’s Kennedy Space Center in a key demonstration for CEO Elon Musk who hopes to land lucrative military launch contracts in the future. The booster carried Arabsat-6A, a 13,000-pound Saudi telecommunications satellite designed to provide television, internet and mobile phone service to the Middle East, Africa and Europe, into orbit. Read more for the launch and to see the three boosters land back on Earth.
NASA’s Curiosity Mars rover, which landed in 2012, came equipped with eclipse glasses, or to be more specific, solar filters on its Mast Camera (Mastcam) that enable it to stare directly at the Sun. These past few weeks Curiosity has used these filters and transmitted some amazing imagery of solar eclipses caused by Phobos and Deimos, Mars’ two moons. Phobos, which is as wide as 16 miles across, was photographed on March 26, 2019, while Deimos, which is as wide as 10 miles across, was captured on March 17, 2019.

Using a global network of telescopes, known as the “Event Horizon Telescope”, an international scientific team on Wednesday revealed a milestone in astrophysics – the first-ever real photo of a black hole – in an achievement that confirmed a pillar of science put forth by Albert Einstein more than 100-years-ago. The image you see above was made possible using data collected in April 2017 from eight radio telescopes in six locations that created a planet-sized observational dish. Their observations strongly validated the theory of general relativity proposed in 1915 by Einstein, which is used to explain the laws of gravity and their relation to other natural forces.
